Let's get the credits organized. It was Jakobi who called out the flywheel keyway. This will have a significant influence on ignition timing. I was mentioning the stator plate location relative to the oval washer stamped with "T".

If the oval washer is modified, the stator plate can be advanced or retarded. Since the trigger (impulse coil) is mounted to the plate, any movement of the plate also throws off the timing.
